SpamAssassin
Postfix uses SpamAssassin to filter e-mail
"If SpamAssassin is working, the message will be marked as spam. Note that SpamAssassin only marks messages as spam and that how it does this marking may be affected by your front-end. If you're not using the "spamc" or "spamassassin" program and are using a third-party front-end (especially amavisd), then it may not be completely obvious how spam messages are handled."[1]

amavisd:
- /etc/logrotate.d/amavisd
- /etc/cron.daily/amavisd
- /usr/sbin/amavisd
- and more. . .
